Total arabinoxylan (TOT-AX) and water-extractable arabinoxylan (WE-AX) digestibility at the level of the ileum and excreta for broilers fed the control, 10, 100 or 1,000 mg/kg of an endoxylanase preparation supplemented diet at 11 and 36 d of age. Small letters a,b and asterisk (∗) indicate a significant difference between the different doses used at a particular broiler age (interaction effect dose × age) at P < 0.05 and P < 0.10, respectively. If present, the main effect of age is also indicated with an arrow on this figure. Error bars denote the standard error of the mean (SEM).
